Answer:

2. a mountain bike
3. how to spell mountain bike
Explanation:
The boy is writing a letter to Santa Claus (known as Viejito Pascuero in Chile) He wants a mountain bike for Christmas, so he asks his father how to spell it in his letter. However, the father secretly spells "mochila" (backpack), which is probably what he already wants to give the boy as a Christmas present.
Since the commercial is about the low prices Jumbo offers, the message is that there´s no need to get something cheap that the boy doesn´t want for his Christmas present.
